COMPRESSOR.

Specification of Letters Patent.

Patented Apr. 4, 1911.

Application filed October 5, 1910. Serial No. 585,512.

To all whom it may concern:

Be it known that I, FRED A. BAKER, a citizen of the United States,residing at Evansville, in the county of Rock and State of Visconsin,have invented a new and useful Compressor, of which the following is aencircles and compresses the shock, may be held about the shock.

WVith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of invention herein disclosed can be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawing, Figure 1 shows the invention in side elevation, thesecuring member being assembled with the clamping member; Fig. 2 is aside elevation of the clamping member, parts being broken away; Fig. 3is a side elevation of the clamping member, showing the opposite facethereof from that depicted in Fig. 2; Fig. 4 is an edge elevation of thedevice; and Fig. 5 is a top plan view of the device, the parts thereofbeing disposed as in Fig. 3.

The clamping member includes a body which, generally speaking, ishook-shaped in outline, as seen most clearly in Fig. 4, the body beingdenoted generally by the numeral 1. This body 1 includes oppositelydisposed side plates 2 and 3, the plate 3 being provided at one end witha reduced portion, constituting the shank 4 of the hook-shaped body 1.This side plate 3 is provided, at one side, with an outstanding arm 5,disposed at right angles to the shank 4, the shank 4 and the arm 5 beingpreferably formed integrally with the plate 3. A pin 6 is terminallymounted in the side plates 2 and 3, one end of the pin 6 being receivedin a bearing 7, formed on the outer face of the side plate 2. This pin 6serves to support for rotation, a sheave 8, the sheave 8 being housedwithin the contour of the side plates 2 and Referring particularly toFig. 4, it will be seen that the shank 4 overhangs the sheave S, theshank 4 being provided with an eye 9 alined with the tread 10 of thesheave 8. Referring still to Fig. 4, it will be seen that the shankpresents an inclined face 11, disposed transversely of the sheave 8. Theplate 2 terminates in a reduced por tion, constituting the point 12 ofthe hook, this point 12 being outwardly inclined, into approximateparallelism with the inclined face 11 of the shank 4.

A pivot pin 14 is inserted into the arm 5, adjacent the end thereof,this pin 14 serving as a mounting for a lever 15, provided with a camface 16, adapted to cooperate with the tread 10 of the sheave 8 to binda flexible element, as will be described hereinafter. This cam face 16of the lever 15 is bounded laterally by flanges 17 and 18, theseflanges, referring particularly to Fig. 5, converging as at 19, from oneend of the cam face 16 of the lever 15, toward the other end of the camface. The flange 1S outstands, as shown at 20, beyond the flange 17.

The plate 3 which carries the arm 5, is provided with a longitudinallydisposed rib 21, extended upon the shank 4, this plate being likewiseprovided with a transverse reinforcing rib 22, extended upon the arm 5.These reinforcing ribs 21 and 22 unite adjacent the center of the plate3, and, at their point of union, the ribs 21 and 22 are enlarged, asshown at 23, to afford a hearing for the pivot pin 6 of the sheave 8.Moreover, the extremity of the transverse rib 22 is enlarged, as shownat 24, to afford a bearing for the pivot pin 14 of the cam lever 15.

The securing member may be an ordinary rope, as shown in Fig. 1, a loop25 being formed in one end of the rope, the loop being engaged in theeye 9 of the shank 4. The securing member is thence passed around theshock, as shown at 26, entered between the point 12 and the inclinedface 11 of the shank 4, as shown at 27 and thence passed between the camlever 15 and the sheave 8, as shown at 28.

The inclined face 11 of the shank 4, together with the outwardlyinclined part 12 of the hook-shaped body 1, serves to receive thesecuring member, and to guide the same against the tread 10 of thesheave 8. Obviously, when the cam lever 15 is disposed as shown in Fig.2, the securing member will be bound between the cam face 16 of thelever 15 and the tread 10 of the sheave 9. During the operation ofmounting the securing member in place, the cam lever 15 will bepositioned as shown in Fig. 8. By comparing Fig. 3 with Fig. 2, it willbe seen that the portion 20 of the flange 18 outstands beyond the flange17 this portion 20 constituting a stop, adapted to receive the securingmember, and to position the same bet-ween the cam lever 15 and thesheave 8, so that when the cam lever 15 is tilted,

from the position shown in Fig. 3 to that shown in Fig. 2, the securingmember will be bound between the lever and the sheave.

It is to be noted that the flanges 17 18 converge, as denoted by thenumeral 19 in Fig. 5. By reason of this fact, the securing member will,not only, be bound bet-ween the cam lever 15 and the sheave 8, but, aswell, be bound, or wedged between converging flanges 17 and 18, when thelever 15 is tilted from the position shown in Fig. .2 to that shown inFig. 3. Owing to the fact that the cam lever 15 is connected by means ofthe arm 5 with the plate 3, and owing to the further fact that the shank4 constitutes a part of the plate 3, this plate is subjected to moresevere strains than the plate 2. Obviously, the ribs 21 and 22 serve toreinforce the plate 3 and the arm 5. The enlargement 23 at the part ofunion between the ribs 21 and 22, serves to form a bearing for the pin 6upon which the sheave 8 is mounted. Likewise, enlargement 24 of the rib22 serves as a bearing for the pin 14 upon which the lever 15 ismounted. The plate 3 is therefore well adapted to receive the strainswhich are thrust upon it during the operation of the device.

By reason of the fact that the shank 4 overhangs the sheave 8, the eye 9in the shank 4 may be alined with the tread 10 of the sheave 8, thuspermitting the flexible securing member to pass, in a single plane,around the shock and through the clamping member, there being,therefore,'no tendency for the clamping member to tilt, caus-.

ing the flexible securing member to slip off the tread 10 of the sheave.

Having described the invention, what I claim as new is:

In a device of the class described, a hookshaped body provided at oneend with a line-receiving shank, and at one side with an arm outstandingsubstantially at right angles to the shank; a sheave journaled forrotation in the body; a cam lever fulcrulned upon the arm andcooperating with the sheave, the cam face of the lever being bounded bylateral flanges converging throughout their entire extent, from one endof the cam face to the other, a portion of one of the flangesoutstanding beyond the other flange, to guide a line between the cam andthe sheave.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.
